"Bridgeport, in the county of Fairfield and State of Connecticuahave `111ir1lve`nted anew1 Improvement in 'OrriageeDoorm 1und1 do hereby declare the follow.

1 jug, `when takeninconnection with the accompanying idrawings and the letters `of" reference marked thereon,

'tube a full, clear, and exactdescription of the same,

.Figure 3, a sectional perspective view of the clnm p; andi'n 1 1 -Figlurcs 4 an'd 5, similar construction of the same '1clamp.1 1 p `'I hisinvention relates Vto an improvement in car-- "riage-doors, the object being the arrangement of afde- .j `vice in combination with the strapby which the glass fisraised, so thatthe glass'niayl he supported at any desired elevation; v and 1 'i 'f-Itfconssts in the arrangementupou the door of a 1 ,clamping device, through `whicirthe strap for4 raising the glass passes, constructed soa's to grasp'the Vstrap .or holder, and hold itpatliany position4 to which the 'glass may beraised'.

FA sthe-Iowerpart of a ca1riage-door, of common construction. ,L 1 y ,"B, -tlie frame"1 of 1 glass, `constructed to,` run. up and down in the door, and provided with a strap, C, -for raising the glass, in the. usual mannerl y "As heretofore constructed, it has been necessary1 'that heglass be either clear down or clear up, there being no "intermediate means for snstaining'the same.4

Todo this, I arrange a .clamping device upon the door, consisting of the fixed bar aand cam el, between which the strap O passes, .as'seen in'igs. 1 and 2,-the.

weight'of the glass tending to closethe cam, bydrawf1 ing over its inner surface,'as seen in" g. 2,' yet allow the strap to be freely drawn through, to elevate the glass. v

" To release the strap sof thattheglass may be lowered, I -form an arm, j, (see fig. 3,) upon the cam', l l

whereby it may be4 depressed, as. denoted in broken lines, fig. 3, to free the 'strap and allow the descent of the glass. 1 Y' In gs. 1, 2, and 3, I have'shown thev cam arranged to clamp the strap between it and a bar above.; yet',

" if preferred, the cani maybe arranged, as seen in iigs.'

4.v and 5, to operate uponfthe bar belo\ When the glass has been fully raised, asY seen vin fig. 2, audit is desirable to close :the opening entirely, it is necessary to throw the glass" onto the rabbetv ln.-

1 To do this, I arrange a short strap,-m, upon. the lower bar of the glass, so that, by taking hold ofthe strap' m and raising the glass, it will take 'the` weight from the cam, consequently freeing the strap therefrom, and permit the glass -to Vbe thrown out, as de` -notei in broken lines, iig. 2.

By this construction, it will be seen that the glass may be held at any desired elevation, and the object of the invention fully accomplished.

I claim as, my invention- 1. In'fthe construction of .carriage-doors, the'com'- lhination of an automat-ic stop, catch, or clamp, with 'theglass frame-holder .or strap, whereby the glass` Vmay be held in any desired position, substantially' as shown.A y 1 ,c

` 2. In combination with the foregoing, the strap m,

arranged uponthe glass-frame, substantiallyy as and for the purpose specified.4 j JOHN H. BLOODGOOD.
